VMware drops hints that ESXi on Arm is about to become a proper product

Also looks to have security and SaaS news in store for next week’s VMworld


Strong hints have emerged that VMware is close to making the Arm version of its ESXi hypervisor a proper product.

VMware announced ESXi-on-Arm in September 2018, and in early 2019 suggested it could find a home in SmartNICs or could be a good fit for AWS’ Arm-powered cloud. But this year the virtualization giant said that customers don’t see a need for the hypervisor and it may never become a supported product.

Things may have changed since, because VMware this week pointed out that it will attend the Arm developer conference that starts on October 6, and deliver a session titled Arm-based solutions from VMware spanning On-prem and Edge.

The session promises that VMware speakers, including “Arm enablement architect” Andrei Warkentin, will discuss “a range of solutions around Arm processors, designed to both address new and growing markets, and complement our existing offerings for customers looking for cross-platform and unified solutions.”

Further evidence that Virtzilla has something up its sleeve comes from a new @esxi_arm Twitter account, with a profile that reads: “A port of VMware's famous Type-1 hypervisor to 64-bit Arm. People don't know me well yet, but I'm sure they'll grow to love me as much as my older sibling.”

Virtzilla has even given ESXi on Arm a logo.

The logo depicts a Ptarmigan – a Canadian bird that has "Arm" in its name – that has served as VMware's code-name for ESXi-on-Arm.

Why might Virtzilla make its Arm hypervisor a real thing? The Register understands that VMware and Nvidia have news to share at next week’s VMworld conference and it could make sense for ESXi-on-Arm to run on kit like the forthcoming Nvidia EGX platform, which combines a GPU and SmartNIC. Or perhaps VMware is going to have a crack at the Arm servers now that its cloudy friends Oracle and AWS will both offer them and say they’ll be cheaper than x86 kit.

VMware certainly loves Kubernetes and microservices right now, and AWS and Oracle both suggest Arm-powered servers are a great place to run such workloads. So does Arm itself. ESXi-on-Arm could play to that proposition.

VMware CEO Pat Gelsinger used his Q2 2020 earnings announcement to tease VMworld announcements about “AI and ML, modern apps, new security offerings, and key new partnerships with leading technology and services companies.”

He also told investors to: “Stay tuned to hear more about SaaS announcements at VMworld in September.”

The company could tick off the first three announcements with a way to harness single Arm cores for various chores.

Now that VMware has delivered Kubernetes support for everyday vSphere users, the big incomplete item on VMware’s modern apps to-do list is full integration with Pivotal. Which could be another VMworld announcement and again deliver on Gelsinger’s modern apps promise.

On security, VMware has a vision but is yet to fully integrate its August 2019 Carbon Black purchase or explain why it killed off “vSphere Platinum”, the bundle of vSphere and its now-seldom-discussed AppDefense security tool.

The Register understands that AppDefense’s approach of improving security by isolating misbehaving VMs has misfired due to false positives. We expect a re-statement of VMware’s belief that policy-driven security deep in the stack, rather than identification of problems on endpoints, is a better way to control risks, but also a clearer view of how Carbon Black will fit in the company’s portfolio.

This could even tie into ESXi-on-Arm, by placing security-centric microservices on the edge in SmartNICs.

As for partnerships, it’s hard to see who VMware doesn’t already list among its pals. The company this week announced that its SD-WAN plays nicer with Equinix, but could also conceivably team with more DevOps companies.

And SaaS? VMware has already introduced apps to do things like workplace contact-tracing as part of its WorkspaceONE suite. The company could expand that range, go deeper with its multi-cloud-management, or do more with software-defined-networking-as-a-service for SD-WAN or perhaps even further down the stack.

The Register’s virtualization desk will attend Virtual VMworld to bring you whatever materialises. ®

    Imagine a future where racks of computer servers hum quietly in darkness below the surface of the Moon.

    Here is where some of the most important data is stored, to be left untouched for as long as can be. The idea sounds like something from science-fiction, but one startup that recently emerged from stealth is trying to turn it into a reality. Lonestar Data Holdings has a unique mission unlike any other cloud provider: to build datacenters on the Moon backing up the world's data.

    "It's inconceivable to me that we are keeping our most precious assets, our knowledge and our data, on Earth, where we're setting off bombs and burning things," Christopher Stott, founder and CEO of Lonestar, told The Register.

    In brief The notorious Russian-aligned Conti ransomware gang has upped the ante in its attack against Costa Rica, threatening to overthrow the government if it doesn't pay a $20 million ransom. 

    Costa Rican president Rodrigo Chaves said that the country is effectively at war with the gang, who in April infiltrated the government's computer systems, gaining a foothold in 27 agencies at various government levels. The US State Department has offered a $15 million reward leading to the capture of Conti's leaders, who it said have made more than $150 million from 1,000+ victims.

    Conti claimed this week that it has insiders in the Costa Rican government, the AP reported, warning that "We are determined to overthrow the government by means of a cyber attack, we have already shown you all the strength and power, you have introduced an emergency."

    In a technical analysis, the researchers detail the various malicious stages and payloads of the campaign that used sanctions-related phishing emails to attack Russian entities, which are part of the state-owned defense conglomerate Rostec Corporation.

  • Mysterious firm seeks to buy majority stake in Arm China
    Chinese joint venture's ousted CEO tries to hang on - who will get control?

    The saga surrounding Arm's joint venture in China just took another intriguing turn: a mysterious firm named Lotcap Group claims it has signed a letter of intent to buy a 51 percent stake in Arm China from existing investors in the country.

    In a Chinese-language press release posted Wednesday, Lotcap said it has formed a subsidiary, Lotcap Fund, to buy a majority stake in the joint venture. However, reporting by one newspaper suggested that the investment firm still needs the approval of one significant investor to gain 51 percent control of Arm China.

    The development comes a couple of weeks after Arm China said that its former CEO, Allen Wu, was refusing once again to step down from his position, despite the company's board voting in late April to replace Wu with two co-chief executives. SoftBank Group, which owns 49 percent of the Chinese venture, has been trying to unentangle Arm China from Wu as the Japanese tech investment giant plans for an initial public offering of the British parent company.

  • SmartNICs power the cloud, are enterprise datacenters next?
    High pricing, lack of software make smartNICs a tough sell, despite offload potential

    SmartNICs have the potential to accelerate enterprise workloads, but don't expect to see them bring hyperscale-class efficiency to most datacenters anytime soon, ZK Research's Zeus Kerravala told The Register.

    SmartNICs are widely deployed in cloud and hyperscale datacenters as a means to offload input/output (I/O) intensive network, security, and storage operations from the CPU, freeing it up to run revenue generating tenant workloads. Some more advanced chips even offload the hypervisor to further separate the infrastructure management layer from the rest of the server.

    Despite relative success in the cloud and a flurry of innovation from the still-limited vendor SmartNIC ecosystem, including Mellanox (Nvidia), Intel, Marvell, and Xilinx (AMD), Kerravala argues that the use cases for enterprise datacenters are unlikely to resemble those of the major hyperscalers, at least in the near term.
